Museum grade display case lighting fixtures herein refer to internally mounted exhibit case lights. These light fixtures are tasked with providing illuminance that helps visitors appreciate the exhibit. Light is the most efficient form of information transmission since it can influence the visual perception of texture, color and shape of artworks. Museum grade display case lighting fixtures work to illuminate exhibits without becoming the headliner. They must be installed unobtrusively into museum exhibit display cases, which include, for example, built-in cases, four-sided glass cases with solid top, five-sided glass cases with solid top, grand cases, mini-cases, table cases with flat tops, table cases with lectern tops, and wall cases.
